Malignant Gastrointestinal Neuroectodermal Tumor of Small Intestine Showing DOG1 Expression: A Case Report and Review of Literature.

Malignant gastrointestinal neuroectodermal tumor (GNET), also referred to as clear cell sarcoma-like tumor of the GI tract is a rare mesenchymal tumor of the gastrointestinal tract. It has to be distinguished from various mimickers including gastrointestinal stromal tumor (GIST) due to its aggressive course and different natural history and therapeutic approach. Here we report a case of GNET arising in the small intestine with aberrant DOG1 expression posing a diagnostic challenge. In this context, the combination of clinical, histomorphological, immunohistochemical, and molecular features helped to establish a proper diagnosis.

Overview of Assault-Induced Trauma Presenting to a Trauma Centre in Oman.

OBJECTIVES: Assault-induced trauma (AIT) is a public health concern that must be addressed and acknowledged. This study aimed to characterise cases of AIT presenting to Sultan Qaboos University Hospital (SQUH), Muscat, Oman. METHODS: This retrospective descriptive study included patients presenting with AIT to the emergency department of SQUH from January 2007 to December 2018. The data obtained included incidence, patients' demographics, mode of assault, triaging, management and hospital stay. The data were collected using the hospital's information system and subsequently analysed. RESULTS: A total of 268 cases of AIT were identified and 239 fulfilled the study criteria. The highest incidence recorded was in 2018, accounting for 72 cases. The mean incidence of AIT was 20 ± 19 per year. The sample was predominantly comprised of males (82.4%) and Omani citizens (65.3%). Most patients (66.9%) were between the ages of 20 and 39. The most common mode of assault was the use of bodily force (34.7%). Additionally, 18.4% were triaged as red cases. In terms of management, 84.5% of the cohort were treated non-surgically. No incidence of in-patient mortality was recorded. CONCLUSION: This study found that the rate of AIT averaged at 20 per year with most of the victims being young males. This was the first study that examined AIT in Oman and its results will aid future research and the estimation of the magnitude of this problem in the community.
